![]() ![]() Wildlife-vehicle collisions have increasingly been an issue of concern for many state and provincial transportation agencies. Roads and highways threaten species population viability as well as overall biodiversity by destroying habitat and fragmenting populations. Additionally, findings of species-specific response to vehicle passage are important in understanding potential fitness consequences of anthropogenic disturbance. Knowledge that vehicle movement influences wildlife behavior underscores the importance of consideration given to road and crossing structure design. Both species were more likely to move through the underpass if they exhibited foraging behavior we also found a marginally significant trend that animals were less likely to use the underpass after vigilance behavior. Both species increased vigilance and flight behaviors and reduced time spent foraging in response to vehicles. We quantified the time that elk ( Cervus elaphus) and white-tailed deer ( Odocoileus virginianus) allocated to foraging, vigilance, and flight behavior before and after vehicle passage. However, little is known about traffic’s proximal effects on wildlife behavior and use of mitigation measures. Mitigation efforts (e.g., wildlife underpasses) are constructed to prevent fragmentation and reduce wildlife-vehicle collisions. Bicycle rentals are available at the Visitor Center Plaza, and guided bus tours on Hermit Road are offered by Grand Canyon Lodges.Roads fragment animal populations, vehicles kill and injure animals, and traffic may affect animal behavior. ![]() This road can be accessed throughout the year by hikers, runners and bicyclists. Hermit Road is open to private vehicles during the Winter months of December, January, and February when there is no shuttle service available on Hermit Road.You must access the Red Line at the Village Route Transfer 2 miles west of the Grand Canyon Visitor Center. It’s important to note that it does not start at the Grand Canyon Visitor Center with the Purple, Orange, and Blue Lines. The Red Shuttle service is required to visit this road between March 1st and November 30th.Consider planning a morning trip if you’d like to experience the quiet beauty of the Grand Canyon here without the crowds. ![]()
